RFC 3496� � � ATM Service Class-aware MPLS Traffic Engineering� March 2003

1. Overview

� � This document defines a Resource ReSerVation Protocol-Traffic

� � Engineering (RSVP-TE) protocol addition to support ATM (Asynchronous

� � Transfer Mode) Service Class-aware MPLS (MultiProtocol Label

� � Switching) Traffic Engineering.

� � This protocol addition is used with all MPLS Label Switched Routers

� � (LSRs) and link types (including, but not restricted to, Packet over

� � SONET, Ethernet, and ATM links) to signal traffic engineered paths

� � that can support the ATM service classes as defined by the ATM Forum

� � [TM].� This document does not specify HOW to actually implement the

� � functionality in the MPLS LSRs to emulate the ATM Forum service

� � classes (such as necessary queuing and scheduling mechanisms), only

� � how to signal that the TE path must support t...
